Letters Patent No. 101,503, dated April 5, 1870.

ADJUSTING-SLIDE FOR CHAINS.

* *Qrb* The Schedule referred to in these Letters Patent and making part of the same.

To all whom Ait 'may con-cern:

Be it known that I, ROBERT JAMES lonn, of Morrisania, in the county of IVestchester and State of N ew York, have invented a new and useful Improvement in Adjusting Sli es for Chains; and I do hereby declare that the following is a Iull, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings forming partof this specii'ication.

This invention relates to improvement in the slides used on the long gold or other chains worn around the neck, and known as opera leontine chains; also applicable to guard-chains; and consists in providing the said slides with barrels or tubes through which the chains work, made in two parts, hinged together, and provided with spring catches or lockiu gdevices, whereby they may be readily opened and closed for application to and adjustment along the more elaborate chains now in use, which have various styles of links connected together at regular intervals, some of which are too large to pass through the barrels of the size which it is preferred to use.

Figure l represents a view of the chain of the character for which my improved adjusting-slides are intended, with one of the same applied.

Figure 2 represents a tranverse section of the slide, the section being taken on the line x x; and

Figure 3 is an end View of a slide, such as now commonlyused onthe plain chain.

These slides, A, are provided with barrels, B, through which the plain guard, or `other chain with links of uniform size, will readily slip for adjusting the slides along the chains, as is required in arranging the chains in different ways, but for elaborate chains having links of various "sizes, some of which (such, for instance,

as shown in the drawing) are very large, the barrels would have to be made too large; besides if made large enough they would not run smoothly and regularly on the chains. I therefore propose to make the barrels to open and close readily, so that, when it is required to adjust the slides along the chains, they can be opened and moved over lthe large links.

For this purpose I make the barrels in two parts, C D, and hinge them together' at E, connecting the two parts D of a pair permanently together, and providing a spring catch, or snap catch at F, for fastening them together, after the slide has been adj usted ou the chain to the required position.

The barrels are made of such size as'to encircle the smallest part only of the chain, and do not, therefore, require to be made so large, as they would to slide as they now do moreover when locked orfastened around the chain in the required position they cannot get out of place, as the slides as now constructed do, sometimes very much to the annoyance of the wearer, and requiring freqpent rcadjustinent.

Having thus described my invention,

I claim as new and desire to secure by Letters Patent- The combination with the chains, substantially such as herein described, of the adjusting-slides A, providedv with divided and hinged barrels having spring catching, or other locking or fastening devices, substantially as specified.

The above specification of my invention signed by me this 21st day of February, 1870.
